GAS-MACHINE.

SPECIFICATION forming part of Letters Patent No. 345,402, dated July 13,1886. Application filed October 9, 1885. Serial No. 179,387. (No model.)

To all whom, it may concern:

I is weighted at one-end and connected by an Be it known that I, JOSEPHS. WOOD, of adjustable pin at its opposite upwardly-bent Brooklyn, inthe county of Kings and State of New York, have invented certain new anduseful Improvements in Gas-Machines, of which 'the following is aspecification.

This invention relates to improvements in automatic gas apparatus ofthat class in which the vapors are generated from volatile hydrocarbonsby the action of heat mixed with a suitable quantity of air in amixingchamber, and conducted from the same to a'gas-holding dru m, thatregulates automatically by its rise and fall the generation of gas inthe retort;

and the invention consists, mainly, in a novel combination of parts foractuating the needlevalves of the mixingchamber and of theretort'heating burner by the rise and fall of the gas-holding drum; andthe invention consists, further, of several minor and novel combinationsof parts, which will be more fully described hereinafter, and finallypointed out in the claims. I

The accompanying drawing represents a vertical longitudinal section ofmy improved gasmachine.

A represents a gas-generating retort, of cylindrical or other shape,which is provided at its bottom with a downwardly-extending hood,

supply of air to the burner.

'A, for protecting the burner-flameagainst draft or wind. The gas-burnerO is arranged below the retort and supplied with gas by a pipe, I), thatextends downwardly from the re tort A. A vertical needle-valve, O, opensor closes the gas-supply orifice in the throat of the burner, abovewhich are arranged air-supply openings d'and an exterior sleeve, d, saidsleeve having air-openings that register with the openings d, and ahandle for turning the same'to the right or left, so as to regulate theThe admission of a proper quantity of air produces the per feetcombustion of the gas and prevents the smoking of the flame. I prefer touse a socalled rose-jet burner, as thereby a steady uniformheating-flame is obtained. At the lower part of the burner is arrangedan alcohol-cup, by which the burner is heated in the usual manner whenthe gas-machine is to be set into operation. The lower end of theneedle-valve O is pivoted to a keeper, 6, that bears by knife-edges on afulcrumed lever, D, which end, with a release-rod, G, that is hinged atits upper end to the gas-holder E. The retort A is supplied with oilthrough an oil-supply pipe, a, which is connected to the oil-tank, inwhich the oil is kept under pressure. A suitable packing, a, is placedin the upper part of the oil-supply pipe at, the packing being made ofcotton or asbestus wicking, or of fine wires, and looped around a wire,a", that is attached to the pipe at, so as to prevent the packing frombeing forced up into the retort and retard the flow of oil to theretort. The packing of the supply-pipe has the advantage that the oil issupplied evenly to the retort, so that a more uniform generation ofvapors in the same takes place, and that thereby the socalled jumpingofthe flames caused by the irregular functioning of the retort isobviated. The retort A is connected at the upper part with a verticalmixing-chamber, H, having a needle-valve, h, which needlevalve isconnected by a knifeedged keeper, h, to a fulcrumed lever, D,

by an adjustable pin, h with a fixedarm, G, of the release-rod G. Thetapering end of the needle-valve h is fitted into the conical throat ofthe mixing-chamber H in the usual manthe same.

To the air-port ofrthe mixing-chamber H is connected an air -supplypipe, I, having a check-valve, I, and air-inlet openings 1', by whichthe required quantity of air is drawn in, so as to be mixed with thevapors. The check- Valve I is balanced by a weighted lever, 'i, which isfulcrumed to a bracket-arm, f, of the tage that the check-valve is keptin a normal position at all times, so as to supply any desired number ofburners, according to the position of the weight on the fulcrumedleveri'.

use of springs, as they are objectionable owing to the fact that in caseof back-pressure in the machine, due to the sudden extinguishment of allthe burners, gas may escape at the checkvalve, and by ignition take outthe temper of the spring, so that it becomes useless. The check-valve isinstantly closed by the backwhich is weighted at one end, and connectedner, so as to regulate the supply of vapors to casing of the check-valveand pivoted to the stem of the check-valve, which has the advan Thisregulating arrangement is superior to the '1 pressure, so as to preventin a reliable manner any escape of gas through the air-supply pipe. Thevapors and air pass from the mixingchamber through an ejection-throat toa gaspipe, m, and are conducted by the same to a condensing-chamber atthe lower part of the gas-holder E. The drum E of the gas-holder movesin aring-shaped casing. E, formed of two concentric walls, which casingis partly filled with water, that forms a seal for the drum.

The condensing-chamber E is divided by a partition,n,into twochambers,to one of which the gas-supply pipe on is connected, while theservice-pipe is connected to the other chamber. The partition a does notextend entirely down to the bottom of the condensing-chamber I)", butleaves an opening, which is closed by a water seal, so' that the gas iscompelled to pass from the first condensing-chamber by a short pipe, n,to the gasholding drum and the space inclosed by the inner cylinder,then by a short pipe, of, at the other side of the partition a to thesecond condensing-chamber. The condensation is collected in the firstcondensing-chamber and at the bottom of the inner cylinder of thegas-holder, and passed through a siphon-shaped drip-pipe, a, connectingwith the bottom of the gas-holder, to the second condensing-chamber,from which it is removed from time to time.

The hinged release rod G of the gasdrum E is guided by means of slottedkeepers g g, a

and pressed outwardly by a spring. 9". The release-rod G is providedwith a tapering projection, gZth-at moves along the lower keeper, 9',When the drum is lowered, so as to swing inwardly and release therebythe lever D from the rod G and the lever D from the arm G. Theneedle-valves of the burner O and mixing-chamber H close thereby theorifices of the burner and mixing-chamber and stop the machine. By thealternating rising and falling of the gas drum E the needle-valves ofthe burner and of the mixing-chamber are more or less opened. so as togenerate a sufficient quantity of gas corresponding to the consumptionby the burners.

The operation of the apparatus is as follows: The oil-tank is filledwith oil under pressure, so that the oil can pass through the supplypipeinto the rctort A. The burner ot' the retort is first heated up by meansof alcohol for starting the apparatus. The oil in the burner isvaporized and forms a flame, which heats the retort and generates vaporsin the same,which afterward supply the flame of the burner by theconnecting-pipe b. The greater portion of the vapors is conducted to themixing-chamber, where they are mixed with atmospheric air and passedthrough the pipe at to the gas-holder, from which the service pipe andits burners are supplied with gas. The generation of vapors in theretort is diminished as the drum rises by the action of the intermediatelevers, and increased when the drum falls and the gas therein isconsumed by the burners.

The setting ofthe needle-valves of the burner and of the mixi ngchamberby levers connected directly to said valves simplifies the constructionof the gas-machine and produces the reliable and automatic operation ofthe apparatus.

Having thus described my invention. I claim as new and desire to secureby Letters Patent 1. The combination of a generating-retort, a burnerconnected by a gas-pipe to the retort, a needle valve for said burner, amixingchamber connected to the retort, a needlevalve for saidmixing-chamber, a gas-holder having a vertically-movable gas-drum, agaspipe leading from the mixing-chamber to the gas-holder, a release-rodhinged to said drum, and l'ulcru med and weighted levers connected,respectively,to the needle-valves of the burner and mixing-chamber, andto said releaserod, whereby the generation ofgas is automaticallycontrolled by the rise or fall of the drum, substantially as set forth.

2. The combination of a generating-retort, a heating-burner connected bya gas-pipe to the retort, a needle-valve for said burner, amixing-chamber connected to the retort, a needle-valve for saidmixing-chamber, a gasholder having a verticallymovable gas-drum, a gaspipe leading from the mixing-chamber to the gas-holder, aspring-actuated releaserod hinged to the gas-drum, and having a taperingprojection, a keeper for guiding said release-rod, and fulcrumed andweighted levers connected to the needle-valves of the burnerandmixing-chamber, and to the releaserod, whereby the generation of gas isautomalically controlled or entirely interrupted by the rise and fall ofthe drum, substantially as set forth.

3. In a gas-machine, a gas-holder formed of a jacketed easing, a movabledrum, condensation-chambers at the bottom of the holder, pipes leadingfrom the interior of the casing to said condensation-chambcr, and asiphon-shaped drip-tnbe extending from the bottom of the easing into oneof the condensation-chambers, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
